To all whom it may'concern 7 Be it known thatI, EDWARD B}: WATSON, a citizen of the United States, residing at Toledo, in the county of'Lu' eas and State of Ohio, have invented certain'new anduseful Improvements in Ventilating-Covers for Cans; and I do hereby declare the following to be a full,'fclear, and exactjdescription of the invention, such as will enable others skilledin the art to which it appertains to make and use the Same. f

My present invention relates to dairy ;apparatns and to cans for'containing milk'and cream, but more particularly to an improved ventilated cover: for cans, and toirnprovements upon the structure represented by U L t er P efitN6-1J23 i t, s ed t me under date of July 3,1917. 7

Prior to my invention above referred to it was customary for farmers and dairymen to accumulate cream skimmings in one can or receptacle, to transfer this from time to time to another can forpurposes of cooling,

nd fin ll inm t i la th cant r s -ins and shipment. As distinguished from this shaped substantially as shown by Fig. 4 of the drawings, to snugly fit within the conical method my invention contemplates gathering, cooling, and finally shipping creamin one and the same can if desired.

A further object of. the present invention is the production of can covers for the purposes indicated having certain structural characteristics, including a readily removable partition for compelling ventilation by inducing a circulation of fresh air upon both sides thereof into and out of the can and over its contents.

With the foregoing and other objects and advantages in view, the present invention will be hereinafter particularly described and pointed out in the claims following.

In the accompanying drawings which form part of this application for Letters Patent, and whereon corresponding numerals indicate like parts in the several views:

Figure 1 is a perspective view of my improved ventilating cover for cans, detached.

Fig. 2 is a vertical central section through cover, and the neck of a can to which it is applied.

Fig. 3 is an inverted plan of cover detached, upon a relatively enlarged scale, and

Fig. 4 is a perspective view of ventilating partition removed.

Reference being had to the drawings an numerals thereon, 5 indicates an ordinary milk or cream can, having the usual outy fla in .01 d verg ngfl ak i ihiifihil which my invention is designed and adapted to fit. The cover constituting {the basisg of this invention comprises a conical top 7 having an annular overhanging flange .8 thebet- Y 7 ,ter to shed rain, a depending annular wall 9 liniformally perforated throughout its entire circumference, a laterally extending horizontally arranged closinglfiange: 10 prolfict'ing outwardly from the base-of said'perfo'rate'd .wall,j..a converging annular body portion 11, and oppositely disposed parallel ears or extensions 12,,12 depending[from said body portion for engaging the vertical side walls ofthe can neckas shown byFig.

2, so as to retain the entire .cover in opera.- tive position without risk of accidental dis,- o ei ent-l a f As best'shown'by Figs-2 and 3, theconical body portion 11 of the completecover is slotted radially, and at point diametrically opposite .as'sh own at: 13, 13, for the purpose of permitting "the ready introduction or Withdrawal of a thin netallic partition '14 top 7, the perforated annular wall 9. and converging body portion 11 below which it extends into the can proper, as shown by Fig. 2.

This being a description of my invention in its best form of construction at present known to me, its use and operation may be briefly set forth as follows:

My improved removable ventilating cover having been applied to a can as indicated by Fig. 2 of the drawings, for example, a can for cooling cream. it is obvious that contents of the can will be carefully guarded and protected from dust, dirt, and foreign matter generally, 1nclud1ng rain or snow,

which might otherwise enter. Moreover, a most satisfactory and beneficient circulation of air over the contents of can is insured at alltimes by reason of the'circulating partition 14. which defines bothan inlet and an outlet for air in its passage through the can. A current of air for instance, entering from the left of Fig. 2 through perforations in the annular wall 9 is deflected downwardly I by the central circulating partition 14 which it cannot pass directly, whereupon this downward current naturally produces an upward counter-current upon the opposite side of said partition, and thence to the outside atmosphere through perforations at the right hand side of said Fig. 2. In this manner and by virtue of the partition 14 a constant current and circulation of air 13 main- -tained, and the accumulation of foul air or gases prevented during the ing, or at other times.

I It will be noted also that the circulating partition'll is readily removable for sanitary purposes, and when this is desired it is only necessary to rotate the same Within its inclosing cover until opposite edges thereof register with the oppositely disposed radial slots 13, 18 when itmay be instantly Withdrawn, thus rendering it possible and entirely convenient to cleanse and thoroughly wash the interior of the cover. The partition 14 may then be instantly replaced by a reversal of the operation aforesaid, and

process of coolwhen rotated slightly as shown by Figs. 2

"should be understood that various changes in the form, arrangement and combination ofparts shown may be made and substituted i for those illustrated without departing from the spirit of my invention, which, having been thus described what I now claim and desire to secure by Letters Patent is:

l. A removable ventilating cover for cans comprising a closed top having a depending perforated ventilating wall, a laterally 6X- tending closure-flange, and a circulating partition extending transversely across said cover dividing it into vertical compartments.

2. A removable ventilating cover for cans comprising a closed top having a depending perforated ventilating Wall, and a removable circulating partition adapted to divide said cover into independent vertical compartments. V I

3. A removable ventilating cover for cans comprising a closed top, a depending ventilated wall, adownwardly converging body portion, and a removable circulating partition adapted to divide; said cover into independent vertical compartments.

4. A'removable ventilating cover for cans comprising a closed top, a depending venti-' lated wall, a-downwardly extending body portion provided with oppositely disposed slots and a removable circulating partition adapted to be introducedthrough said slots into the coverand to'divide the latter into independent vertical compartments.

In testimony whereof I affix my signature, in presence of two subscribing witnesses.
